Abstract: 1354556 Twisting WESTERN ELECTRIC CO Inc 25 Aug 1971 [31 Aug 1970] 39787/71 Heading B3E [Also in Division H1] A method of unwinding and reversing the pitch of an elongate member wound helically on a mandrel 12 comprises pulling the member from the mandrel and twisting the member so as to reverse the pitch of the member by means of a rotating spindle 33 mounted on a carriage 31, and engaging the trailing end of the unwound member in a slot 43 when the member is pulled from the mandrel. In operation a plurality of mandrels having helically wound members 11 wound thereon are positioned so that their lower ends engage bearing blocks 22 and their upper ends engage associated slots 24 in a bracket 27. The top end of each coil is then secured under a bracket of a spindle after which the carriage 31 is moved away from the mandrels and the spindles rotated in an anticlockwise direction, Fig. 1. As the unwinding progresses the axis of each unwound member becomes more inclined so that the trailing end portions of each member are moved into an associated slot 43. The rotation of the spindles is adjusted to induce an overtwist so as to impart sufficient torsional energy to reverse the last few convolutions adjacent the trailing end portion of each member. As the last convolutions are unwound the trailing end portions engage one of an associated pair of pins 46. The overtwist is then removed by reverse rotation of the spindles and the carriage returned towards the mandrels so that the members can be released.

A pressure regulating valve comprises a main valve closure (8), controlling the flow from a conduit (1), (2) to a by-pass (9). A conduit (3) leads from the supply conduit to a chamber 6 and contains a throttle (4). A piston (7) is located in the chamber (6) and the pressure in this chamber acts on the piston to urge the valve (8) to its closed position, the area of the piston (7) being considerably greater than the area of the valve (8) subjected to the pressure in conduit (1), (2). A pilot valve (11) controls the flow from the chamber (6), the valve (11) being loaded by a solenoid (13). The valve (8) thus opens when the force due to the pressure in the conduit (1), (2) exceeds the force due to the pressure acting on the piston (7). The throttle (4) may be replaced by a constant flow valve.

Title: A PROCESS FOR DRY SPINNING POLY-gamma-METHYL GLUTAMATE FILAMENTS
IPC: D01F6/68
Filed: 1969-08-18
Abstract: 1283763 Poly-γ-methyl glutamate filaments AJINOMOTO CO Inc and NISSIN SPINNING CO Ltd 18 Aug 1969 [23 Aug 1968] 41079/69 Heading B5B [Also in Division C3] Poly-γ-methyl glutamate filaments are produced by extruding into a heated atmosphere a solution of the polymer in a solvent consisting of a mixture of a chlorinated aliphatic hydrocarbon which is a good solvent for the polymer and another chlorinated aliphatic hydrocarbon which is a non-solvent for the polymer and which has a boiling point higher than the good solvent. The good solvent, which should have a boiling point lower than the melting point or decomposition point of the filaments formed, may be methylene dichloride, chloroform, 1,2- dichloroethane 1,1,2-trichloroethane or tetrachloroethane and the non-solvent for the polymer may be 1,1-dichloroethane, 1,2-dichloroethylene, carbon tetrachloride, 1,1,1-trichloroethane, 1,2-dichloropropane, 1,3-dichloropropane or tetrachloroethylene. Trichloroethylene may also be used as a non-solvent, if a slightly higher proportion is used, relative to the good solvent, than with other non-solvents. The weight ratio of the non-solvent to the good solvent may be from 1 : 9 to 1 : 1. The coagulating ability of various non solvent chlorinated aliphatic hydrocarbons with respect to a solution of the polymer in a chlorinated aliphatic hydrocarbon which is a good solvent for the polymer is determined by measuring the number of C.C.S. of the non-solvent which when added dropwise with stirring to a solution consisting of 7À2 grams of poly-γ-methyl glutamate having a degree of polymerization of 2,500 and 28À2 CCS. of 1,2-dichloroethane at 20‹ C. causes the polymer solution to develop a white turbidity and gelation. In the experiments turbidity occurred when 13 to 85 CCS. of the non-solvent chlorinated aliphatic hydrocarbons were mixed with the polymer solution. Hence a non-solvent is defined as one having a coagulating ability in this test of less than or equal to 85 mls; the coagulating ability of a good solvent is very low and may be regarded as effectively infinite. In further experiments solutions of poly-γ- methyl glutamate in various mixtures of the solvent and non-solvent chlorinated aliphatic hydrocarbons were heated to 50‹ C. and extruded through a spinneret into a spinning cell containing air heated to 90‹C. The filaments thereby formed could be stretched at stretch ratios up to 2À25.

Title: Method for the manufacture of lactose-containing tablets
IPC: C13K5/00
Filed: 1964-10-19
Abstract: Lactose, which contains at least 50% by weight beta-lactose, is prepared by drying or crystallizing a syrup or solution of lactose in water at a temperature above 200 DEG  F.  The preferred method comprises roll drying a syrup preprepared by dissolving in water lactose that has been recrystallized from whey concentrate, the syrup containing about 35 to 50% by weight of lactose.  The syrup is fed into the bite of a double drum dryer, whose rollers are steam heated to 265 DEG  to 340 DEG  F., and thus dried to give a product containing about 0.3% of water, and about 75% of beta-lactose, the remainder being alpha-lactose.ALSO:Lactose-containing tablets, wherein the lactose comprises a major proportion of beta-lactose, and constitutes at least 25% by weight of the tablet, are prepared by forming a free-flowing mixture of an active ingredient and the lactose, and forming into tablets in the absence of added moisture. Suitable lactose, having a beta-lactose content of at least 50%, may be prepared by crystallising the lactose from aqueous solution, preferably a syrup, at a temperature above 200 DEG F. (e.g. by roll-drying on steam-heated rollers; see Division C2).  The lactose may be colored by adding a water-soluble dye to the aqueous solution. An example is given for preparing tablets containing aspirin or soy-flour as the active ingredient, using a 75% by weight beta-lactose-containing roll-dried lactose.  The tablets made from such lactose are said to be more resistant to capping and more readily water-soluble than those of the usual, mainly alpha, lactose.

Title: Method of producing polyhydric alcohols
Inventor: ROCHE ANDRE
IPC: C07C31/18
Filed: 1960-12-12
Abstract: Polyhydric alcohols are extracted from the mother liquors obtained by the reaction of formaldehyde with aliphatic aldehydes or ketones by treating the mother liquor with an acid to bring its pH to a value between 0.1 and 3 in the presence of an aldehyde or ketone which is not miscible with water or a mixture of an aldehyde or ketone with a water-insoluble organic solvent so as to produce an acetal or hemi-acetal which is not soluble in water but is soluble in the organic phase, the impurities going into the aqueous phase, separating the organic phase containing the readily hydrolysable acetal or hemi-acetal, and heating this with water or water mixed with an organic solvent so that the acetal or hemi-acetal is hydrolysed and can be extracted in the organic phase. In a modification applicable to the separation of pentaerythritol, the organic solution of pentaerythritol after the first extraction is concentrated so that pure crystals of pentaerythritol are separated out, the crystals and the remaining organic solution being then separately subjected to the treatment with water so as to give pure pentaerythritol and an organic solution of dipentaerythritol. Polyhydric alcohols which may be separated by the process are, for example, pentaerythritol and anhydroenneaheptitol.  Suitable aldehydes and ketones for use in the extraction are, for example, benzoic or toluic aldehyde, a methylated, halogenated, or nitrated derivative of these aldehydes, furfuraldehyde, cyclohexanone, methyl or dimethyl cyclohexanone or acetophenone, or mixtures of these with a diluent solvent, preferably cyclohexanol.

Abstract: 1477024 Electrolytically coating continuous tapes GALENTAN AG 2 Oct 1974 [4 Oct 1973]  42787/74 Heading C7B A continuous conductive tape 1 is electrolytically coated wholly or partially on one or both sides with e.g. Au by passing the tape in fluid tight fashion over an insulating roller partially immersed in an electrolyte solution while electrolyte is sprayed from nozzles 13 against the tape, which nozzles are separate from the anodes 14. There may be held fluid-tight against the tape, in the case of a partial coating, one or more non-conducting tapes 8 which move with the substrate tape and mask it where required. The masking tape(s) may be of endless elastic material and have apertures which locate with projections 18 on roller 2. Notches on tape 1 engage pins 17 on roller 2 to ensure the proper location of the tape with the apertures. Tape 8 is tensioned at 10 and may drive the assembly, in which case the tape 8 need not contact the tape 1 when an overall coating is required. A hollow roller may be used with a slot or apertures therein allowing electrolyte to be supplied for coating the inner surface of tape 8. Alternatively, for this purpose, the roller may be grooved. A plurality of tapes may be simultaneously coated. The apertures in the masking tape may be closer e.g. by 0À1-1À20% than actually required, whereby this tape can be held stretched under tension against the substrate tape. When edge coatings are to be applied, the tape 8 may project beyond the edge of the roller on one or both sides.
